The woman screamed when she saw the stranger next to her, and the man ran out of the house, said police Lt. Chuck Kaye. The home is in a neighborhood near Rancho Peñasquitos Boulevard and Via Del Sud, Kaye said.

The suspect used a cloth to cover his face during the assault, police said. The attacker was described as thin and between 5 feet 9 inches and 5 feet 11 inches tall. He wore a dark hooded sweatshirt with a striped shirt underneath, and dark-colored shorts, police said.
